HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 328,676 dated October 20, 1885.

Application filed July 21, 1885. Serial No. 172,255. (No model.)

To all whom it may concern.-

Be it known that I, CARL HEYER, a citizen of the United States, and a resident of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Horseshoes, of which the following is a specification.

The object of my invention is to furnish a calk for horseshoes which may be detached from the shoe and sharpened without necessitating the removal of the entire shoe for this purpose, which, owing to the absence of a skilled mechanic, is very often impossible.

In the accompanying drawings, forming part of this specification, and in which similar letters of reference indicate similar parts throughout the several views, Figure 1 is a bottom view of a horseshoe fitted with my calks; Fig. 2, a section of Fig. 1 on the line 1 2, and Fig. 3 is a side elevation of a modified screw for securing the calk to the shoe.

Ais the horseshoe; B, the calk upon the toe; O, the calks upon the heel; D, a screw screwed into the shoe and having its head pro- ;5 jectingvout from the shoe and passing through a corresponding hole in the calk; E, a hole or slot in the head of D through which a wedge or key, F, is driven to hold the calk securely in place.

The calk B, which is applied to the toe of the shoe, is furnished with legs a b, which clasp the sides of the shoe, the heel-calk being also furnished with similar legs, their purpose being to assist in securing the calks to the shoe and to prevent them from turning.

The calk G on the heel of the shoe has the leg a of the calk which is upon the outside of the shoe set flush with the shoe, so that the horse will not injure himself with it, as would be the case if it were to project beyond the outside of the shoe.

In applying the calks to a shoe holes are drilled and tapped in the shoe to receive the screw D, which is screwed in place with the hole E in its head parallel with the sharpened point a of the calk. The calk is now put into place, the legs a b clasping the sides of the shoe, the top of the calk and the bottom of the shoe being made to fit, while the head of the screw D passes through a corresponding hole in the calk. The wedge or key F is now driven in and the entering end is preferably bent over the side of the calkito }prevent it from falling out. If through any cause the point a should become bent or dull it is only necessary to drive out the wedge F, when the calk can be removed from the shoe and sharpened.

Fig. 3- shows a screw to take the place of the screws shown in Figs. 1 and 2. This screw has a slot, E, in the side of its head instead of the hole already described. This slot is turned toward the point 0 of the calk, and the wedge F is driven in one side, bearing against the screw, and the other against the point c.

When in place, my calk is extremely firm and strong, and it can be readily detached from the shoe and sharpened by a person inexperienced in the art of horseshoeing, and again attached, when for all practical purposes it forms part of the shoe.

Having thus described my invention, I claim and desire to secure by Letters Patent- The herein-described device for securing the calks B or C to the shoe A, consisting of the screw D, secured to the shoe, and having a hole, E, in its head, and the wedge or key F, passing through this slot and bearing on the calk, substantially as set forth.

CARL HEYEE.
